Fusion FWD L4-2.5L Hybrid (2010)
Yes
GO to AC3.
No
GO to AC5.
-------------------------------------------------
AC3 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TO GROUND
-
Measure the resistance between the DLC C251-3, circuit VDB06 (GY/OG), harness side and ground; and between the DLC C251-11, circuit
VDB07 (VT/OG), harness side and ground.
-
Are the resistances greater than 1,000 ohms?
Yes
GO to AC4.
No
GO to AC32.
-------------------------------------------------
AC4 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TO VOLTAGE
-
Connect: Negative Battery Cable .
-
Ignition ON.
-
Measure the voltage between the DLC C251-3, circuit VDB06 (GY/OG), harness side and ground; and between the DLC C251-11, circuit VDB07
(VT/OG), harness side and ground.
-
Is the voltage greater than 6 volts?
Yes
REPAIR the circuit. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The MS-CAN has tested within specifications. GO to Pinpoint Test AB to diagnose the intermittent MS-CAN fault. See: Pinpoint Test AB: Intermittent
No Medium Speed CAN (MS-CAN) Communication, One + Modules Are Not Responding During Network Test
-------------------------------------------------
AC5 CHECK THE MS-CAN TERMINATION RESISTOR
-
Measure the resistance between the DLC C251-3, circuit VDB06 (GY/OG), harness side and the DLC C251-11, circuit VDB07 (VT/OG), harness
